Selection coding in C#:

private void listBox1_SelectionChanged(object sender, SelectionChangedEventArgs e)
        {

            int index = listBox1.SelectedIndex;
            string str;
            if (index == 0)
            {
                 str = (string)Text1.Text;
            }
            else if (index == 1)
            {
                 str = (string)Text2.Text;
            }
            else
            {
                 str = (string)Text3.Text;
            }

            MessageBox.Show(str);
